It matters because when Wolf was a new character, no one wanted to give him different weapons and moves to make him more unique from the existing Star Fox cast.
Because, again, he isn't all that unique from the Star Fox cast. Those weapons from Assault are better off being items, not moves. If you wanted a more unique Star Fox character, Krystal would like a word with you.
Likewise with Toon Link, no one wanted him to have moves representing different Zelda items; he makes sense as being a faster, weaker version of the main Link.
Oh ho, how
wrong you are. Before Toon Link was leaked for Brawl, there were movesets all over the place with him using his Deku Leaf (which is funny because BotW's paraglider), the Grappling Hook, the Wind Waker, The Skull Hammer, and even using the King of Red Lions as his Final Smash.
Instead, he was simply a re-skinned Young Link (whom people also wanted a revamped moveset for, which could have him use his masks. They still do actually.) and left as a clone with only minor adjustments, which disappointed a TON of people.
Comparing source material, Toon Link was slower than Twilight Princess Link (running speed-wise), but they were equal in attack speed. The unique attacks Toon Link could do (such as the parries), Twilight Princess Link pulled off with slightly more speed and do so at will. As far as fighting goes, technically speaking, Twilight Princess Link is superior to Toon Link in literally every way.
Yet, for the sake of the archetype, Toon Link was adjusted to be smaller, faster, and weaker... Oh, who are we kidding? Toon Link was WAY stronger than Link in Brawl. The difference between their strengths didn't appear until Sm4sh.
